Weather Briefing
MVFRGroton New London Airport is currently reporting marginal VFR (MVFR) conditions with overcast skies at 2,900 feet and 10 SM visibility.
Wind Analysis
Winds are from the south (190°) at 11 knots. Runway 23 is favored with a 8-knot headwind and 7-knot crosswind component.
Visibility & Ceiling
Visibility is 10 SM. The ceiling is 1700 feet AGL (broken), placing conditions in the MVFR category.
Temperature & Moisture
Temperature is 6°C (43°F) with a dewpoint of 3°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.
Forecast Outlook
The TAF forecast covers the next 21 hours. The forecast shows a transition between VFR and IFR conditions. Pilots should monitor the forecast closely and have an alternate airport plan. Expected weather includes: Light Showers Rain, Mist. There is a 30% probability of VFR conditions with Light Showers Rain between 09:00Z and 12:00Z. Temporary MVFR conditions are forecast with Light Showers Rain between 12:00Z and 16:00Z.
Pilot Recommendations
VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

About Groton New London Airport
Overview
Groton New London Airport serves southeastern Connecticut as a medium-sized airport located near the coastal region. Situated at a low elevation of 9 feet MSL, the airport provides critical aviation infrastructure for the Groton and New London metropolitan areas, supporting both general aviation and potential regional commercial operations.
Flying Conditions
The airport experiences predominantly VFR conditions, with 75.7% of observed weather periods suitable for visual flight rules. Wind patterns are consistently westerly at 270 degrees, averaging 9.3 knots with occasional gusts up to 41 knots. Temperature variations are significant, ranging from -14°C to 25°C, which pilots should consider for performance planning.
Notable Features
Both runways are asphalt-surfaced with substantial lengths: Runway 05/23 at 5000 feet and Runway 15/33 at 4000 feet. The coastal location suggests potential for rapidly changing weather conditions, with an average visibility of 9.3 statute miles and occasional periods of reduced visibility or fog affecting approximately 2% of observations.
Approach Considerations
Both runways demonstrate favorable wind alignment, with 100% wind compatibility for approaches. Average crosswind components are moderate, at 5.5 knots for Runway 05/23 and 6.3 knots for Runway 15/33. November, December, and September statistically offer the most consistent VFR flying conditions for pilots planning operations at this airport.
